Hey,
what kind of problem do you want to simulate? Can you maybe try to use the standard icoFoam solver and see if it lets you simulate passed the current time? |

Well I tried using the icoFoam Solver...Still its increasing the time precision to 18..
--> FOAM Warning : From function Time:perator++() in file db/Time/Time.C at line 1055 Increased the timePrecision from 6 to 18 to distinguish between timeNames at time 12.1401 Time = 12.1401000000000003 Courant Number mean: 0.0076843727 max: 0.070992469 smoothSolver: Solving for Ux, Initial residual = 0.00017927652, Final residual = 9.515912e-009, No Iterations 1 smoothSolver: Solving for Uy, Initial residual = 0.00046194189, Final residual = 1.477745e-008, No Iterations 1 DICPCG: Solving for p, Initial residual = 0.04602532, Final residual = 9.436656e-007, No Iterations 734 I wanted to solve the energy equation to calculate the Nusselt number. That is why I had to modify the icoFoam solver. Thanks!! |

hey,
Here's one more problem that I've come across. This is completely unrelated to the previous problem about timePrecision. When I check the time steps that have been saved, the last time step is 3.35. The solver is currently at 7.1175 sec. Here's my controlDict Code:

Okay I think I got my answer to the last question. I changed the writeControl ti timeStep and its saving data as expected.
